Plate Boundaries (Chapter 17 Section 3)

What are huge pieces of crust and rigid upper mantle that fit together at their edges to cover Earth's surface?

• Tectonic Plates

• Continental Drift

• Pangea

• Puzzle Pieces

What are regions where two tectonic plates are moving apart?

• Divergent Boundary

• Convergent Boundary

• Transform Boundary

What are regions where two tectonic plates are moving toward each other?

• Divergent Boundary

• Convergent Boundary

• Transform Boundary

What are regions where two tectonic plates slide horizontally past each other?

• Divergent Boundary

• Convergent Boundary

• Transform Boundary

What are narrow depressions that are formed at Divergent Boundaries on continental crust called?

• Rift Valley

• Ocean Ridge

• Deep Sea Trench

• Volcanic Island Arc

What is the process when two tectonic plates collide, the denser plate descends below the other, less-dense plate?

• Subduction

• Sublimation

• Transduction

• Abduction

Where are most divergent boundaries found?

• on the seafloor

• on continents

• along coastlines

• at subduction zones

What happens along a divergent boundary on the seafloor?

• Continental mountain ranges form

• New ocean crust forms

• Oceanic plates are subducted into the mantle

• Ocean basins become smaller

Which of the following features forms when two oceanic plates converge?

• magnetic reversal patterns

• divergent boundaries

• subduction zones

• rift valleys

Which of the following landforms results from divergence of continental crust?

• a mountain range

• a rift valley

• a deep-sea trench

• a long fault
